BOTTLE-TRAP.

SPECIFICATION forming part of Letters Patent N0. 408,215, dated August 6, 1889. pplication led October l2, 1888. Serial No. 287,908. (No model.)

In the accompanying drawings, Figure l is a sectional view illustrating the form of the body ot my improved trap. Fig. 2 shows the same with the inlet-pipe in position in connection with the outlet-pipe and .the parts constituting the bottom of the trap detached. Fig. 3 is an outside view of the trap complete.

The bodyl ot the trap isa continuous piece of metal-preferably of lead--generall y cylindrical in shape, but reduced at one end by spinning or otherwise to form a contracted opening 2, of a diameter to be closed by the l inlet-pipe 3, which, as shown, is tapering in shape, increasing in diameter toward the inner end, and which when placed in position, shown in Figs. 2 and 3, is there secured by a line of solder 4. At one side of the body is an opening 5, affording communication between the trap and the discharge-pipe G, also consisting of a tube of soft metal, which is placed in position and secured by a line of solder 7, as shown in Fig. The bottom portion or end of the body is as large or large'r in diameter than the remaining` portion of the trap, and this end is closed to form the bottom of the trap by means of a ring 8 and a plug or cap il, the ring Shaving an annular flange lO, which extends upward into the open end of the body l, and the ring is then secured to the body by a line of solder l2, as shown in Fig. 3. The ring 8 has internal threads lf3 to receive the threaded portion 14 of the cap 9, which also has a flange 15, upon which to place a packing' 1G, which serves to seal the joint between the cap and the ring when the cap is in its position, as shown in Fig. 3, ears 17 17 upon the cap serving as a means of turning the same and thereby compressing the packing in the joint.

The trap constructed as above described can be cheaply made, owing to the simple character of each of the parts and to the ready means of connecting them together, and it is also capable of being quickly and thoroughly cleansed, inasmuch as the opening in the ring 8 closed by the cap can be made of a diameter nearly equaling that of the body, which cannot be done when both ends of the body of the cap are contracted, as usual.

By increasing the diameter of the'inlet-pipe 3 toward the lower end I am enabled to avoid the siphoning which is apt to result when in let-pipes of uniform diameter are employed. The cap 9, instead of being a screw-cap, may consist ot a fiat plate secured to the ring 8 by screws, clamps, or any other suitable appliances.

Without limiting myself to the precise con struction and arrangement of parts shown, I claim-- rlhe within-described improved trap, provided with a body contracted at the upper end, and the lower end of which is equal to or greater in diameter than the remaining portion, with a bottom consisting of a ring secured to the lower end of the body, and acap connected detachably io the ring, and with an outlet-*pipe and an inlet-pipe increasing in diameter toward the lower end, suliistantially as set forth.

In testimony whereof I have signed my name to this speci (ication in the presence of two subscribing witnesses.

ROBERT CLARKE.
